Zoonotic fungus Arthroderma multifidum causing chronic pulmonary infection

Abstract

A rare case of fungus Arthroderma multifidum infection occurred in a 63-year-old man. The patient had some risk factors, including occupational exposure, immunosuppressive state, and structural basis following pulmonary tuberculosis and pneumothorax surgery. The pathogen was repeatedly isolated from bronchoalveolar lavage fluid and identified by gene sequencing. It is the first report of human infection caused by A. multifidum. Whole genome sequencing and analysis of its genomic characterization are completed. The findings provide us with a key clinical insight that the combination of immune suppression and environmental exposure could create an ideal condition for zoonotic fungal infections.
